But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

I narrowed down the list of mufflers to two (2) for my Ford 460. The first was a Gibson MWA. Nice muffler - but too loud. I settled for the Magnaflow. Once the exhaust was installed with a rear-exit tailpipe, the 3"in/3" out centered muffler had a low-rumble with no indication of resonance inside the cab, even while downshifting from a higher rpm range.
